Interaction of an un ultra-wideband source with buried cylinders is solved with a time-domain formulation of the Cylindrical Wave Approach. The pulsed excitation typical of remote sensing with the Ground Penetrating Radar can be implemented, i.e., the Gaussian monocycle or Gaussian doublet waveforms. The analysis is developed in the frequency domain, and spectra of the scattered field contributions are found. Time-domain waveforms are reconstructed with an inverse Fast Fourier Transform. Results are plotted as the typical A-scan or B-scan radargrams of the Ground Penetrating Radar technique.

Abstract
Interaction of an un ultra-wideband source with buried cylinders is solved with a time-domain formulation of the Cylindrical Wave Approach. The pulsed excitation typical of remote sensing with the Ground Penetrating Radar can be implemented, i.e., the Gaussian monocycle or Gaussian doublet waveforms. The analysis is developed in the frequency domain, and spectra of the scattered field contributions are found. Time-domain waveforms are reconstructed with an inverse Fast Fourier Transform. Results are plotted as the typical A-scan or B-scan radargrams of the Ground Penetrating Radar technique.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
